Short answer: the Tribit Xsound Surf. It ranks #79 of 136 medium speakers by sound quality at $26; the Ultimate Ears Boom 4 ranks #88 and costs $105, so there is not much of a tradeoff to weigh.
What the Tribit Xsound Surf offers: Rugged rubberized frame with a metal grille. Set against that: Bass doesn’t go as deep as others, strange midrange peaks.
The case for the Ultimate Ears Boom 4: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. The catch: Not much improvement over the old ones.
Buy the Tribit Xsound Surf. It ranks higher for sound quality than the Ultimate Ears Boom 4 and costs less, so there is no real case for the other one.
If battery life is a priority, the Ultimate Ears Boom 4 is rated for 15 hours versus 10 hours for the Tribit Xsound Surf.
